COTTON-CHOPPER ATTACHMENT FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 327,681, dated October6, 1885.

Application filed July 28, 1885.

To all whom it may concern.-

Be it known that I, HANS HENRIKSEN, of Duarte, in the county of LosAngeles and State of California, have invented certain new and usefulImprovements in Cotton-Chopper Attachments for Cultivators, of which thefollowing is a full, clear, and exact description.

Referenceis to be had to the accompanying drawings, forming part of thisspecification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of a cultivator to which my improvement has beenapplied, parts of the cultivator being broken away. Fig. 2 is asectional side elevation of the same, taken through the line a" m,Fig. 1. Fig. 3 is a rear elevation of the same, the cultivatorbeamsbeing shown in section. Fig. 4 is'a diagram illustrating the cuttings.Fig. 5 is a plan view of a circular cutter. Fig. 6 is asectionalelevation of the same, taken through the line y y, Fig. 5.

The object of this invent-ion is to provide cotton-chopper attachmentsfor cultivators constructed in such a manner that they can be readilyapplied to any ordinary cultivator and can be made to chop the cotton toany desired stand.

The invention consists in the construction and combination of thevarious parts of the attachment, and in their combination with acultivator, as will be hereinafter fully described and then claimed.

A represents the wheels, 13 the axle, and C the frame, of thecultivator.

D aretheshafts. E are the draw-bars. F are the pl0w-bean1s; and G arethe handles, which are strengthened in position by braces G.

H are the ropes or chains, I are the guidepulleys, and J are the levers,for raising and lowering the cultivator-beams.

K are the catch-bars, and L are the pawls, for holding the adjusting-levers in place, and M is the drivers seat, about theconstruction of which parts there is nothing new.

To the axle B are attached the ends of a rod, N, in such a position thatthe said rod will be in line, or nearly in line, with the axis of thewheels A.

Upon the rod N is placed the forked or slotted forward ends of the armsof the U-shaped Serial No. 172,876.

(No model.)

bar 0, which are secured to the said rod by bolts P, so that the bar 0can swing upon the rod N as a pivot. Several holes are formed in theforked or slotted ends of the bar 0 to re ceive the bolts 1?, so thatthe said bar 0 can be adjusted forward or backward upon the rod N, asmay be required.

To the vertical parts of the bar 0, at alittle distance from its bend,are attached the ends of a crossbar, Q. to which and to the said bendare attached bearings, in which revolve vertical shafts R. Several holesare formed in the crossbar Q and in the bends of the bar 0 to receivethe bolts that fasten the shaft-bearings, so that the shaftsR can beadjusted at a greater or less distance apart, as may be desired.

To the ends of the cross-bar Q and to the 7 arms of the bar 0 areattached arms S, which cross and rest upon the plow-beams F, and havetheir outer ends bent downward to keep them in place upon the saidbeams, so that the free end of the angular frame 0 Q will be raised andlowered by and with the said beams F, to cause the cutters to conform tothe surface of the ground.

To the lower ends of the vertical shafts R are attached the centers ofthe cutters T, so that the said cutters will be carried around by andwith the shafts R in their revolution. One of the shafts R is made alittle shorter than the other to prevent the blades of the two cutters Tfrom coming in contact as they pass each other, as illustrated in Fig.3.

To the upper ends of the shafts It are attached gear-wheels U, the teethof which mesh into the teeth of gear-wheels V, placed upon the squareshaft V, and secured in place by pins X, passed through holes in thesaid shaft W upon the opposite sides of the said wheels. Several holesare formed through the shaft W to receive the pins X, so that the wheelsV can be adjusted to correspond with the adjustment of the shafts R. Theshaft revolves in bearings secured in the angles of the bent arms of theU-bar 0. One of the journals of the shaft WV is extended to enter alongitudinal perforation in the extension-shaft Y, where it is securedin place by a pin, Z, passing through a slot in the perforatedextension-shaft Y, and through a hole in the journal of the shaft W, sothat the shaft W will be carried around by and with the shaft Y in itsrevolution to give motion to the cutters T. With this construction theremoval of the pin Z will release the shaft W, so that it will not berevolved by the revolution of the shaft Y, and the cutters will remainstationary while the machine is being drawn forward.

The extension-shaft Y revolves in bearings in the rear end of the bar a,the forward part of which is forked and has slot bearings provided withbolts in its forward ends to receive and rock upon the rod N, so thatthe bar a will be always parallel with the upper or horizontal part ofthe angular frame 0 Q and can be adjusted with the said frame. 7

To the outer end of the extension-shaft Y is attached a gear-wheel, b,the teeth of which mesh into the teeth of the gear-Wheel 0, placed uponthe inner end of the hub of the wheel A and secured to the spokes of thesaid wheel by the annular clamping-plate d and the bolts 0, passingthrough the said plate and wheel, so that the choppers will be drivenfrom the wheel A.

The shafts R are designed to be made of such a length that the cutters Twill revolve a little below the surface of the ground, so as to loosenthe soil and to cut out the plants in those places where the blades ofthe said outters cross the row of plants and overlap, as indicated bythe diagram in Fig. 4, the diamond-shaped spaces in the said diagramrepresenting the places where the plants are left for a stand.

The cuttersT can be made to revolve slower or faster to leave more orfewer plants for a stand by exchanging the gear-wheel b for a larger ora smaller gear-wheel and adjusting the angular frame 0 Q and thebracebar a accordingly.

\Vhen it is desired to only loosen the soil without chopping the plants,the cutters T are detached and replaced by circular cutters f, which maybe of a less diameter than the length of the said cutters T. In thiscase the shafts R and gear-wheels V must be adjusted at such a distanceapart that a sufficient space will be left between the adjacent edges ofthe cutters f to allow the said cutters to pass along the opposite sidesof a row of plants without injuring the plants.

Having thus described my invention, what I claim as new, and desire tosecure by Letter Patent, is

l. A cotton-chopper attachment for cultivators, constructedsubstantially as herein shown and described, and consisting of the rodN, the angular frame 0 Q, hinged to the said rod and provided with armsS to rest upon the plow-beams, the shafts R R W Y, journaled to theframe 0 Q, the cutters T, at,- tached to the shafts R R. the geanwheelsU V,U V, connecting the shafts R R with the shaft W Y, and thegear-wheels b c, for connecting the said shaft W Y wit-h the wheel of acultivator, as set forth.

2. The combination, with the axle B, the wheel A, and the plow-beams Fofa cultivator, of the rod N, attached to the cultivator-axle, theangular frame 0 Q, hinged to the rod N and provided with arms S restingupon the said plow-beams, the shafts R R W Y, journaled' to the saidangular frame, the cutters T, attached to the shafts R R, thegear-wheels U'V, U V, connecting the shafts R R with the shaft WV Y, andthe gear-wheels b 0, connecting the shaft W Y with the wheel A of thecultivator, substantially as herein shown and described, whereby thecotton-chopperattachment will be operated by the advance of thecultivator, and will be made to conform itself to the surface of theground, as set forth.
